Road Trip ,Short Horror Story

Driving with my best friend is the best. Music all the way up, singing like I'm in my own rock band, no worries, just free with life. Seeing an old abandoned house up the street.  jenny says " I dare you to walk into that house for 5 min" Laughing with an obnoxiously nervous laugh I say "hell no" "I'll give you 50$" says jenny "How about 100$ and we have a deal?" I say still kinda nervous "Deal!!" Yells jenny with excitement on her face. We pull up in this stone driveway, the sun is starting to set so there is a pinkish orangeish tint in the sky. How pretty I thought hypnotized by gods beauty, I would be completely okay with seeing this for the last time in my life. Coming back to reality, I walk in and shut the door behind me. The house is dark Like no light has touched these walls in years. The walls are brown, sunk in and falling apart like they are just melting off the frame of the house. There is a offal smell, like rotating food mixed with mold and mildu. Almost like I can't describe what it is. I look at my phone, 3 min left Thank god I thought, I can do this. As I walk into different rooms I hear a noise. "Hello" I called out but I hear nobody in return. Thinking to myself it was probably just a animal. I walk up the stairs, still confused  about that weird noise. Every step is errie. I had to stop, I can feel the stirs about to cave, every creek is stomach dropping. I regain my strength and keep going. I get to the top, "thank god" I say under my breath. I look at my phone again. 1 more minute, I fill with excitement to get out of this dreadful house. I look into the first room on the right. Its a empty room white walls with smoke stained curtains , this was probably a very cute house at one point, what a shame I thought. I HEAR IT! I hear that noise again except closer by me. Like a muffled screeching bat. I walk down the hall with a sick feeling the more closer and closer i get. I turn into the room and I'm in awe at what I see. Blood red walls, mirrors everywhere, black curtains shut over the windows. This room is very much alive and vibrant. I see weird dark red brown stains on the floor, I'm completely confused with what I'm seeing. Step by step I walk into the room a little more and realize the noise is coming from a little boom box in the corner of the room but who would do this I thought, who would live like this?. Just as I was about to turn and walk out of the room, I jumped in the air like a scared cat to see jenny is standing there smiling.  "You scared me! " I screamed. As my heart starts to settle and we both are laughing over me being easily scared I'm relieved to see my best friend. "Come on, I owe you that 100$" she says. Smiling and still laughing I turn in front of Jenny as I'm the first one to walk out of the bedroom door and a sharp pain stabs my back, It puts me to my knees. As I look over to the right onto another dark red and brown stained mirror, I'm confused, scared and screaming in pain. Still looking into the mirror I see jenny put on this mask looks to be made out of different parts of human skin. As I just look at myself and try to make of what's going on. I realize, like a light switch just turned on in my brain. the dark red is dried old blood. As my eyes widen jenny still behind me then looks into the mirror, into my eyes like she is ripping out my soul. As if she could read my mind, that she knew I just realized what was going on. She stands over top of me, bends down, grabs a chunk of my hair enough to lift my head up and forcefully arches my back. I scream in pain because there is a hatchet in my spine. she gets closer to my face I hear her smell my hair, giggle a little in my ear and whispers "You have great skin"
